PATENT OFFICE JOHN S. FORBES, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGN- MENTS, TO YATES & GRANT, INCL, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN Y MAGNETIC nnzon' CONDITIONING AND DEVICE THEREFOR Application filed March 17, 1927. Serial No. 176,193.

My invention relates to magnetic razor conditioning, my object being to provide a simple and efiective means for producing or maintaininga good edge on a razor blade by magnetic influence. How this and other advantages may be realized through my invention will appear by my description hereinafter of a device conveniently embodying it. In the drawings, Fig. I is a tilted front View of a device constructed in accordance with my invention.

Fig. II is a similar view of a razor blade and carrier for insertion in the device shown in Fig. I. r

Fig. III is a tilted rear View of the device, with the rear wall of its case removed.

Fig. IV is a tilted view of the back of the case, with its inner side turned forward.

Fig. V is a tilted view of the blade carrier alone.

Fig. VI shows a horizontal section through the device with a razor blade and carrier in Fig. I.

The device shown in the drawings comprises a casing 10, of generally rectangular form, adapted to receive one or more razor blades while under magnetic treatment In the present instance, the case 10 also encloses completely the means for creating and applying the magnetic influence, comprising one or more (in the present instance two) magnetic members 11, 12 extending lengthwise of the casing, in its mid-region, and also one or more members 13, 141 of magnetic material extending transversely of the casing 10 and of the first-mentioned magnetic means, so as to lie along the edge or edges of a razor blade 15 placed laterally adjacent the magnetic pole end. .As shown in Figs. III and VI, there are two such members 13, 14:, arranged opposite one another at opposite sides of the casing 10. Accordingly the locations and arrangement of the several members 11, 12, 13, 14 is such that a razor blade 15 (here shown as of the familiar double-edged, safety-razor type% may lie laterally adjacent or against' (and eneath) the lower ends of the members 11,12 with its edges in proximity to the members 13, 14,which then lieor extend along said edges. The lower ends of the members-11, 12 may be either of like polarity or of opposite polarity. These members 11, 12 may preferably consist of thin, flat' permanent magnets, and the members 13, 14.- of thin, flat strips of soft iron.

As shown in Figs. III and IV, the upper ends of the members 11, 12 are seated and engaged in grooves in the upper end of the case 10, and their front and rear edges in grooves or recesses 17, 17 (Fig. IV) in the casing back 18. The members 13, 1 1 lie against the casing sides with their lower edges in grooves in its bottom, and with their ends in recesses 19, 19 in the back and front. 18 and 20. Thus, all the members are held securely fixed in the proper relative posi tions. In-the' present instance, the casing back 18 consists of a separate part secured to the body of the casing in any suitable manner, as by rivets 22 embedded fast in'the case extending through holes in the back 18 and'riveted over; while the front 20 is integral with the other casing walls. .The'case 10 and its front piece 18 may bemade of any suitable non-magnetic material, such as a bakelite,"for instance.

As shown in Figs. II .and VI, the blade 15' is held in'position with reference to the memmoldable compound or composition like.

bers 11, 12, 13, 14 by a carrier 25 inserted between the members 13, 14: adjacent the ends ofthe members 11, 12. This carrier 25 may be yieldingly and removably held'by suitable engagement within the case 10, as between its bottom and the ends of the members 11, 12. As shown in Figs. II and V, this carrier 25 has a substantially' flat portion 26 to rev ceive the blade 25, with upstanding projections or lugs 27, 27 adapted to engage in the holes 28,28 in the blade 25to hold the latter in definite position on the carried, and here shown as in the form of punched-up circular flanges. The carrier 25 has also an end or cover portion 29 adapted to occlude the opening 21 and overlap itsedges. Atthe lower side of the blade support 21 of the carrier-25. is a bow-spring 30 whose mid-portion is bowed downward to such an extent that the effective thickness ofthe carrier normally exceeds the interval between the members 11, 12 and the bottom of the case 10. When the carrier 25 is inserted in the case 10, the spring 30 is squeezed and flexed between the members 11 and 12, so as to hold the carrier against accidental withdrawal and keep the blade 15 against the ends of the members 11, 12. The interval between the members 11, 12 is shown as ample to accommodate the ends of the carrier projections 27, 27. The edge of the opening 21 in the casing front is notched at 31 to pass the projections 27, 27. As shown in Figs. II and VI, the blade-supporting portion 26 of the carrier is somewhat Wider than the blade 15, so that while the upper lateral surface of the blade lies flat against the ends of the members 11, 12, the edges of the blade do not come in contact with the members 13, 14. As shown in Figs. II and V, the carrier 25 may conveniently be made by bending a stri of suitable material to form the flat bla e supper-Ling; portion 21, the bow-spring portion 30, and the T-head closure portion or 1 cover 29. The carrier 25 may be made of any suitable non-magnetic material which will afford the necessary resilience, such as coldrolled copper, brass, or bronze.

In practice, a blade is placed on the hold- 9- er 25, inserted in the device, and left there half a minute or so; then Withdrawn, reversed (i. e., turned other side up on the holder) and reinserted in the device for a like period. In reversing the blade, it should be turned edge for edge, as Well as side for side.

It may be left in the device indefinitely without harm; although most of the possible improvement, at any rate, isgenerally achieved in the short time above mentioned. The im- 95 provement is very great e. g a Gillette blade that pulls the beard badly will general- 1y be rendered highly satisfactory.

Having thus described my invention, I claim; i

1. A device of the character described comprising a magnetic pole and a soft iron member adjacent its end and extending trans.

versely thereof, so as to lie along the edge of a blade laterally adjacent said pole end.

2. A device of the character described comprising a magnetic pole and soft iron members at opposite sides thereof, adjacent and extending along the edges of a blade laterally adjacent the end of said pole.

3. A device of the character described comprising magnetic poles side by side, and soft iron members at opposite sides of said poles, adjacent the edges of a razor blade laterally Q0 adjacent the poles.

4. A device of the character described. com-' prising a magnetic pole, soft iron members at opposite sides of said pole, and a razor blade carrier insertible between said mem- 85 hers at the end of the pole and adapted to keep the blade edges out of contact with the members. 1

5. A device of the character described comprising a casing, with a magnetic pole therein, an opening for endwise insertion of a razor blade laterally adjacent the end of the pole, and a soft iron member at the side of the said casing, adjacent the edge of a razor blade so inserted. I

6. A device of the character described comprising a casing with a magnetic member in its central region and an opening for endwise insertion of a razor blade at one end of said member, and soft iron members at the sides of said casing, adjacent the edges of a razor blade so inserted.

7. A device of the character described comprising a pair of magnetic members extending alongside one another and a pair of soft iron members extending alongside one another in quadrant relation to said magnetic members, so that a razor blade may be placed fiatwise between the members of one of said pairs with the members of the other pair along its edges.

In testimony whereof, I have hereunto signed my name at Philadelphia, Pennsylvania, this 28th day of Februar 1927.
